I want to determine carb size before advising but I don't want you backfiring.
Go 81/88 rear plugged
Test your front PV to make sure it works.
What size you using?...with that cam maybe a 4.5" or 5.0" PV
How's that MalloryUnlite it set up? initinal, mech adv, total
Vacuum advance hooked or disc?
Ported or full?
More than likely you have pink #330 cams and they are faded.
Do you have any factory Holley bronze sintered filters in the fuel bowl inlets?
